William H. Seward, an American statesman and diplomat, is best known for his role in the acquisition of Alaska, famously known as "Seward's Folly." His advocacy for American expansionism and diplomatic prowess helped secure the purchase of the territory from Russia. Seward's vision and statesmanship have left a lasting impact on American foreign policy and territorial expansion.

"But you answer, that the Constitution recognizes property in slaves. It would be sufficient, then, to reply, that this constitutional recognition must be void, because it is repugnant to the law of nature and of nations."



"I submit, on the other hand, most respectfully, that the Constitution not merely does not affirm that principle, but, on the contrary, altogether excludes it."



"The United States are a political state, or organized society, whose end is government, for the security, welfare, and happiness of all who live under its protection."



"Simultaneously with the establishment of the Constitution, Virginia ceded to the United States her domain, which then extended to the Mississippi, and was even claimed to extend to the Pacific Ocean."



"But there is a higher law than the Constitution, which regulates our authority over the domain, and devotes it to the same noble purposes."



"The proposition of an established classification of states as slave states and free states, as insisted on by some, and into northern and southern, as maintained by others, seems to me purely imaginary, and of course the supposed equilibrium of those classes a mere conceit."



"I deem it established, then, that the Constitution does not recognize property in man, but leaves that question, as between the states, to the law of nature and of nations."



"But the Constitution was made not only for southern and northern states, but for states neither northern nor southern, namely, the western states, their coming in being foreseen and provided for."



"I speak on due consideration because Britain, France, and Mexico, have abolished slavery, and all other European states are preparing to abolish it as speedily as they can."
